In 32-bit arm, the build fails with:
error[E0308]: mismatched types
--> drivers/gpu/drm/nova/file.rs:42:28

42 | getparam.set_value(value);
| --------- ^^^^^ expected `u64`, found `u32`
| |
| arguments to this method are incorrect

note: method defined here
--> drivers/gpu/drm/nova/uapi.rs:29:12

29 | pub fn set_value(&self, v: u64) {
| ^^^^^^^^^ ------
help: you can convert a `u32` to a `u64`
|
42 | getparam.set_value(value.into());
| +++++++
The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
